Brown sugar: Adds deep molasses flavor and sweetness to both layers.

Salt: Enhances flavor in the crust.

Eggs: Essential for setting the gooey filling.

How To Make the Butter Tart Squares

Step 1: Make the Shortbread Crust

Preheat your oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper. In a bowl, mix 1 cup all-purpose flour, 1/4 cup brown sugar, and 1/2 cup unsalted butter until crumbly. Press the mixture evenly into the prepared pan and bake for 15 minutes, or until lightly golden.

Step 2: Prepare the Filling

While the crust is baking, whisk together 2 large eggs, 1 cup brown sugar, 1 tablespoon all-purpose flour, 1/2 teaspoon baking powder, 1/4 teaspoon salt, 1 teaspoon vanilla extract, and 2 tablespoons unsalted butter (melted). Stir in 1/2 cup raisins if using.

Step 3: Combine and Bake

Pour the filling over the pre-baked crust. Return the pan to the oven and bake for 25 to 30 minutes, until the top is golden and the center is set but slightly jiggly.

Step 4: Cool and Slice

Allow the squares to cool completely in the pan before slicing into 16 bars. The filling will firm up as it cools, making clean cuts easier.
